A reinforced composite material comprises a blend of a thermoplastic matrix and cellulosic fibers, wherein the thermo-plastic matrix comprises a tarry residue fraction from a lignocellulosic biomass liquefaction process. A process for the manufacture of the reinforced composite material comprises subjecting a lignocellulosic biomass to liquefaction in the presence of a liquefaction solvent to form a liquefaction product and a tarry residue; separating the tarry residue from the liquefaction product; and blending the tarry residue with cellulosic fibers to form a recyclable reinforced thermoplastic composite material.

A method of manufacturing a polymer composite comprising a polymer phase and agro-waste particles dispersed in the polymer phase, wherein the polymer phase is preferably obtained from polyolefin containing waste plastics, and the agro-waste particles are preferably obtained from date palm wood flour particles. Various combinations of embodiments are provided.

Provided is a method of manufacturing a resin member. The method includes irradiating a surface of a member containing a resin and a plant powder dispersed in the resin with laser light to change the plant powder or both the resin and the plant powder into diamond-like carbon in a surface layer region including the surface of the member.

A moisture barrier layer-foamed polymeric composite sheet underlayment article comprising a foamed polymeric sheet and a moisture barrier layer adhered thereto is disclosed. In one aspect, cork particles are present in the composite.

A polyvinyl chloride polymer (PVC) composite material is described herein. The PVC composite material includes 40-60 parts by weight of PVC, 40-60 parts by weight of calcium carbonate, 0.2-0.6 parts by weight of composite foaming agent, 3-5 parts by weight of foam regulator, 2-4 parts by weight of toughener, 0.8-1.2 parts by weight of lubricant, and 2-3 parts by weight of stabilizer. Meanwhile, the present invention provides a foam board made of the PVC composite material and flooring. The resulting PVC products have a high-strength structure and a good foaming property, bring the comfort to feet as the resilient flooring does, have a satisfied sound reduction and can be easily installed as the hard flooring could.

This invention relates to a biodegradable hydrophobic or omniphobic coating with tailorable properties for various applications. The technology's hydrophobic modifications, surface functionalization, and surface roughness modifications enable low contact angle hysteresis for easy roll-off and self-cleaning properties. The composite is based on polymer substrate(s) or functionalized polymer substrate(s), filler(s), inorganic(s), binder(s), Lycopodium, or a combination of materials. The Lycopodium may be functionalized with suitable end groups for better adhesion or to impart beneficial properties. The polymer(s) and other constituents may be deposited on the substrate by various methods including spin coating, dip coating, spray coating, sputter coating, electrospinning, solvent casting, or extrusion. Binders and chemicals are incorporated in suitable chronology with or without the solvents of choice.

A foaming process for converting fibrous material into a cellular foam structure includes mixing fibrous material and a solvent-based binding agent to form a mixture; saturating the mixture with a pressurized gas to form a gas-saturated mixture; expanding the gas-saturated mixture by reducing the pressure of the pressurized gas to form an expanded mixture with voids in the fibrous material; and curing the expanded mixture to set the fibrous material and drive off the solvent to provide a stable network of fibrous material having cushioning properties.

A method of manufacturing a building panel with a decorative surface layer, a core and a balancing and/or protective layer, wherein the method includes applying a first layer of a first powder based mix, including wood fibers and a thermosetting binder, on a core; applying a liquid substance on the first powder based mix; drying the first powder based mix; turning the core with the dried first powder based mix such that the first powder based mix points downwards; applying a second layer on the upper part of the core; and curing the first and second layers by providing heat and pressure, wherein the first layer forms the balancing and/or protective layer and the second layer forms the decorative surface layer in the building panel.

The disclosure provides eco-friendly synthetic wood containing coffee grounds, which uses, as main components, coffee grounds and waste gypsum, which are waste resources, and PETG recycled from waste plastic, thereby contributing to protection of the environment, and which enhances formability, post-processability, and a weather resistance of the synthetic wood by reducing a ratio of shrinking-swelling and a water absorption factor of the synthetic wood, and a manufacturing method thereof.

The present invention provides methods for preparing the nut waste composites from a nut waste component, one or more binders, and an oil using a compounder/extruder.
